Madhur L.
Hexokinase removes a phosphate group from ATP and places it onto glucose to produce glucose 6-phosphate. What is the classification for this enzyme? Select one: a. ligase b. oxidoreductase c. transferase d. hydrolase 2. Which of the following is a common feature of both the light reactions of photosynthesis and the respiratory electron transfer chain? Select one: a. Water is formed. b. A Q pool (Q/QH2) is used. c. All of these d. The electron transfer reactions are nonspontaneous. 3. Which of the following is true regarding the reciprocal regulation of both glycolysis/gluconeogenesis and glycogen degradation/synthesis? Select one: a. In response to glucagon signaling, a kinase is activated resulting in the stimulation of both gluconeogenesis and glycogen degradation. b. In response to glucagon signaling, a phosphatase is activated resulting in the stimulation of both gluconeogenesis and glycogen degradation. 4. Which of the following is specific for DNA synthesis, but not RNA synthesis? Select one: a. NTPs are required b. A primer is required. c. All of these d. Synthesis occurs only in the 5' to 3' direction. 5. The substrate for glucose-6-phosphatase must be transported into the ER lumen from the cytoplasm for gluconeogenesis to continue. This is an example of which type of metabolic regulation? Select one: a. The activity of enzyme b. The accessibility of substrates c. The amount of enzyme 6. Which of the following is specific for the complete oxidation of carbohydrates, but not that of fatty acids? Select one: a. ATP can be produced under anaerobic conditions. b. All of these c. Acetyl-CoA is produced. d. NADH is produced. 7. Which of the following is specific for triacylglycerol synthesis, but not glycogen synthesis? Select one: a. It involves the formation of glycosidic bonds. b. It involves the activated carrier UDP. c. It occurs at the endoplasmic reticulum. d. It is a regulated process stimulated by a phosphatase. 8. Which of the following is a negative allosteric effector of Fructose 1,6 Bisphosphatase? Select one: a. AMP b. Citrate c. Alanine d. Fructose 1,6 Bisphosphate 9. Which of the following is a common feature of both nucleic acid and protein synthesis? Select one: a. All of these b. They both occur in the cytoplasm of eukaryotic cells. c. They both involve the formation of covalent bonds between monomer units. d. They both require a primer to initiate synthesis.
